Prion-like features and possible hazards of amyloid-β-, tauand α-synuclein aggregates Increasing evidence suggests that the misfolding and aggregation of different disease-associated proteins such as amyloid-β (Aβ) and tau in Alzheimer’s disease (AD), α-synuclein in Parkinson’s Disease (PD) and dementia with Lewy bodies (DLB), or prion protein (PrP) in prion diseases is based on a common molecu...

The paper presents a working example of distributed application which can be used to find stationary probabilities of states for queuing models – by generating a transition rate matrix and solving a linear system. The presented example is connected to the RED mechanism which can be used in the TCP/IP protocol to control packets flow. The paper also shows efficiency of the application with the u...

This comparative survey explores three formal approaches to reasoning with partly true statements and degrees of truth, within the family Łukasiewicz logic. These are represented by infinite-valued logic (Ł), Rational Pavelka (RPL) a graded formulas that we refer as Graded (GRPL). Truth constants for all rationals between 0 1 used technical means represent truth. ostensibly features no truth ex...

We study the Directed Feedback Vertex Set problem parameterized by the treewidth of the input graph. We prove that unless the Exponential Time Hypothesis fails, the problem cannot be solved in time 2 log t) · n on general directed graphs, where t is the treewidth of the underlying undirected graph. This is matched by a dynamic programming algorithm with running time 2 log t) · n. On the other h...

The research results which are presented in this paper aimed to verify the theory which claims that there is a significant relationship between financial market integration on international scale, financial development and economic growth. Our research focused not on the entire financial market but on the segment of equity securities (shares and investment certificates) and debt securities (cor...

Previously published data concerning honey bee metabolism, dealt mainly with adult specimens. In most cases, biochemical changes connected with the polyethism of Apis mellifera worker bees were described (Costa and Cruz-Landim, 2005; Elekonich and Roberts , 2005; Roberts and Elekonich, 2005). Little is known about the changes in the metabolism in successive developmental stages of brood (see Hr...
